Versuchsvorschrift

Into a three-necked flask, 40 ml of toluene, 6.0 g (37 mmol) of triethoxysilane and 0.34 mmol of platinum (II) dichloro(h-cycloocta-1,5-diene) were placed, and 20 ml of a toluene solution containing 9.9 g of 4-[N,N-bis(3,4-dimethylphenyl)amino]styrene was added dropwise with stirring at room temperature. After the addition was completed, the mixture was stirred at 70° C. for 3 hours, and thereafter the solvent was removed under reduced pressure to obtain oily pale yellow 4-[N,N-bis(3,4-dimethylphenyl)amino]-[2-(triethoxysilyl)ethylbenzene in an amount of 14.0 g (yield: 94.2%).
